Struct LoggingGuard 

pub struct LoggingGuard { /* private fields */ }

A handle to the dynamic logging subsystem.

Held by BootstrapGuard for the lifetime of the application. Owns the worker guards (which flush buffered output on drop), and exposes reload for swapping the entire logging configuration plus controller for driving runtime filter changes through the override worker.

Implementations

impl LoggingGuard

pub async fn reload( &mut self, config: LoggingConfiguration, ) -> Result<(), GenericError>

Reloads the logging subsystem from the given configuration.

Rebuilds the output layer stack from config and routes the new level filter through the override worker as the new base filter, so an active override is preserved (the new base will take effect once the override expires). Worker guards for the previous outputs are dropped after the swap, which flushes any buffered log lines to their original destinations.

This is the right entry point when the entire logging configuration may have changed (for example, outputs, format, level). For runtime base-filter changes only – such as following a log_level config update – use controller and call update_base directly.

Errors

Returns an error if the new output layers can’t be constructed (for example, the configured log file path is inaccessible) or if the override worker is no longer running.

pub fn controller(&self) -> LoggingOverrideController

Returns a logging override controller that can be used to change the default filter directives.
